Answer:

6.4

Step-by-step explanation:

x/11= tan 30°

x= 11* tan 30°= 11*0.58= 6.4

Option 1 is correct

Answer:

x = 6.4

Step-by-step explanation:

Notice that since you are dealing with a right angle triangle, you can use the trig function tangent, to solve for "x".

Notice that "x" is the side "opposite" to angle 30 degrees, and the side adjacent to that angle has a 11 units measure.

The tangent function relates this two quantities the following way:

tan(30^o)=\frac{opposite}{adjacent} \\tan(30^o)=\frac{x}{11} \\11*\,tan(30^o)=x\\x= 6.35

So rounding this answer to one decimal gives: x = 6.4

You can afford a $950 per month mortgage payment. You've found a 30 year loan at 7% interest. a) How big of a loan can you affor
Lubov Fominskaja [6]

Based on the amount to be paid per month, the size of the loan you can afford is $142,792.19.

The total amount you pay to the loan company is $342,000.

The interest on the money is $199,207.81.

<h3 /><h3>What is the size of the loan?</h3>

The size of the loan is the present value associated with that loan payment that you can afford:

950 = (7/12% x Present value) / ( 1 - (1 + 7/12%)⁻⁽³⁰ ˣ ¹²⁾

950 = (7/12% x Present value) / 0.8767

Present value = $142,792.19

The total amount of money paid is:

= Number of periods x Payment per period

= 30 years x 12 months per year x 950

= $342,000

The interest is:

= 342,000 - 142,792.19

= $199,207.81.

Mumz [18]

Answer:

<u>$50,000</u>

Step-by-step explanation:

Formula to find interest :

I = Prt

Solving :

  • I = (20,000)(0.06)(25)
  • I = (1.5)(20,000)
  • I = (30,000)

Future value :

  • P + I
  • 20,000 + 30,000
  • <u>$50,000</u>

Juan put three square tiles with sides 8 centimeters, 10 centimeters, and x centimeters together so that they form a right trian
Elan Coil [88]
Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to x^{2}.
A = x^{2} ---> equation (1)
By using pythagoras rule which states that the x^{2} = hyp^2 - opposite^2---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
x^{2} = 10^{2} - 8^{2} substitute this value in equation (1) then
A = x^{2} = 10^{2} -8^{2}
where A is the area of the square whose side is x
